When dialing from a land-line telephone, the telephone number is encoded and transmitted across the telephone line in form of dual-tone multi-frequency signaling (DTMF). The tones control the telephone system by instructing the telephone switch where to route the call.

The rejection of an image frequency by a single –tuned circuit , i.e., the ratio of the gain at the signal frequency to the gain at the image frequency , is given by. α = 1 + Q 2 ρ 2.

WebThe image rejection happens when the signal is actually in the desired band and its 'image' gets filtered. But if the signal itself comes in the negative frequency (ie the image band for the desired signal) the filtering would not help.
